Abstract: | This article empirically investigated the invariance and discriminant validity of a six-factor leadership model across two very divergent cultures: the United States and Turkey. In conjunction with the rationalist approach to international management, it was hypothesized that the same range of six leadership styles would appear in both cultures. However, coinciding with the culturalist approach to international management, it was also hypothesized that managers would emphasize different styles in each culture. Turkish and US managers each completed the Leadership Effectiveness Questionnaire measuring degree of emphasis placed on six leadership styles. Results of the test of model invariance indicated that the six styles existed in both cultures; however, discriminant analysis demonstrated that the Autocratic and Consensus styles differentiated managers best. Turkish managers emphasized the Autocratic style to a greater extent and the Consensus style to a lesser extent than did US managers. Implications for international management are discussed. ©1998 John Wiley & Sons, Inc. |
